Activity of alpha-1, 4-glucosidase in furazolidone-induced glycogenosis.

Furazolidone (FZ) at 700 and 800 p.p.m. was added to feed mixtures fed turkey poults two and three weeks posthatching, respectively, to induce acute experimental cardiomyopathy. Poults in the control pen received the same ration but without FZ. From EKG data obtained at 2, 4, and 5 weeks of age, control unaffected and experimental affected poults were selected for sacrifice. Poults were sacrificed by cervical dislocation and appropriate samples of hepatic tissue were removed for assays of activity of alpha-1, 4-glucosidase. Results indicate that enzyme activity in affected FZ-treated poults is similar to that in unaffected control poults. Lack of significant differences in activity of this lysosomal enzyme suggests that FZ-induced glycogenosis may be related to the adult form of idiopathic generalized glucogenosis, the etiology of which remains unidentified.
